What I'd like to see is an argument to syslogd to specify a maximum full level 
for the target file system.  Log data is valuable, but being able to write to 
/var/tmp/vi.recover is also important.  syslogd -l 90% could specify that 
sylogd should not write log records, perhaps other than an "out of space 
record" to a log file on a file system with >=90% capacity.  This prevents the 
kernel from spewing about being out of space also.  The accounting code does 
exactly this, for identical reasons.
